Raceline Ryno Beadlock vs. STI HD9 Beadlock

Debating on purchasing either the HD9 locks by STI or the Ryno locks by Raceline. Hoping for any input I can get on which might be the best option, if there is a best option of the two. Will be mounting 32" Chicanes to these.

Thanks everyone

Re: Raceline Ryno Beadlock vs. STI HD9 Beadlock

I am getting a set of the Raceline wheels. Ordering them on Monday. A nice wheel at a decent price.

I am not a fan of the looks of the STI wheel.

Both are good quality wheels, also they both come in 14x7 4-156 5+2. I would say pick the one you like the looks of best.

Re: Raceline Ryno Beadlock vs. STI HD9 Beadlock

I've had the STI HD5s for a while and they were ok...but the bolts stink and break all the time when mounting a tire. The HD9s I've heard have better bolts.

I just got an extra set of wheels / tires and went w/ Rynos - they're awesome and IMO head and shoulder of the HD5s (again I know they aren't HD9s)

the backspacing is a little disingenuous on the Rynos...they are listed as 5/2 but aren't really 5/2s...more like 4.3/2.7 ish.......but road them yesterday and they worked great.

Thats why I went another direction,, Backspacing is not as stated,, Im only running a 30" tire

with the 32's its not as bad

I really like the look of the Raceline

Re: Raceline Ryno Beadlock vs. STI HD9 Beadlock

Thanks everyone for all the feedback so far. Im new to owning a RZR and this is the first set of wheels and tires I have ever purchased for a UTV. Ive read shock therapies wright up on offsets and "scrub radius". Are the Racelines not to "true" 5/2 offset will that affect the scrub radius? The 32" tire with the 5/2 offset sounds like the best route to go. Questions the STI durability after reading some things on the site.

definitely not true and Iíve read it as well and had the same concerns ...whether or not itís substantial for my riding style has yet to be determined. Iíve got multiple acquaintances that use a true 4/3 offset that havenít ever had any issues and other than more mud flying past my face so far nor have I . One things for sure the build quality on the race line was way better than the sti...although running the sti for A year hasnít left me stranded

What do you mean about the backspacing on the Rynos? Looking at these also.

Re: Raceline Ryno Beadlock vs. STI HD9 Beadlock

backspacing for the rynos is just what I stated...more than they list. which means they just stick out a little more than the other ones (makes machine wider) which will affect your scrub radius.

I know enough about SR to be dangerous and I know a bunch of folks in our group that run 4/3s (which makes it even worse) that have zero issues and I currently haven't experienced any (albeit I've only been out once) but had no noticeable difference in feedback w/ the steering etc.

I've also upped to 32 in. tires which is supposed to help but still not tall enough to offset the theoretical perfect SR

I really like the Rynos in other words...and the STIs weren't terrible either - just not built as well. bolts broke all the time (when changing tires - not riding) , the raceline's have bigger bolts, and more bolt holes underneath so you could turn your ring if you fouled one, and the tire bead seats better on the raised part of the wheel and the beadlock rings are more substantial.

I thought STI had corrected the bolt breaking issue with the HD9's, no? Are they still having issues with them breaking the larger bolts also?

my first and second sentence about 7 posts back I state both that I've heard the HD9s have bigger bolts and that I am comparing to the HD5s that I have ....so that's probably correct I just don't have experience with them. I believe the pictures the OP posted do show more bolts in the Rynos though...like 20 vs. 16 if I counted right which is something I noticed about my HD5s as well. you think about it ...that's 25% more bolts than the HD9

Both the Raceline and the STI "5+2s" are +30mm of offset.

If you actually do the math, they are a 4.68+2.32 so, while they aren't a true 5+2 they are closer to that than 4+3. A true 5+2 has +38mm of offset. Methods 5+2 is actually a 5+2. Personally, I don't think the 0.3" is enough to worry about but, if you want to take Shock Therapy's advice and stay under 1" of scrub radius, you need a true 5+2.

Re: Raceline Ryno Beadlock vs. STI HD9 Beadlock

I have had two sets of STI HD5's, old set were 14" and had the small bolts. I never changed tires, they came mounted when I bought them and rode for over a 1000 miles with no issues. I now have a set of 15" STI HD5's with the larger bead lock bolts and they are awesome! 5+2 offset keeps my buggy really close to stock width.

Re: Raceline Ryno Beadlock vs. STI HD9 Beadlock

Ended up buying the Ryno Beadlocks in 14x7, going to wrap them in 32x10x14 Tensor Regulator tires. Hopefully have them mounted by Tuesday evening!
